ANTOINE J. LANGIEIER, OF PROVIDENCE, RHODE ISLAND.

MACHINE FOR SWAING AND POINTING.

SPECIFICTION forming part of Lett-ers Patent No. 462,440, dated November3, 1891.

Application tiled May 23, 1891.

To all whom, it may concern: v Beit known that I, ANTOINE J. LANGELIER,of the city of Providence, in the county of Providence and State ofRhode Island, have invented certain new and useful Improvements inSwaging and Pointing Machines; and I hereby declare that the followingis a full, clear, and exact description of the same, reference heilighad to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in swaging and pointingmachines for reducing the diameter of and pointing wire, rods, dce.

The object of this invention is to produce a swaging'and pointingmachine which will be more economical in its operation than` thoseheretofore made.

My invention consists in certain novel features of construction andpeculiar combination of parts which will he more fully describedhereinafter, and pointed out inthe claims.

Figure l is a front view of the improved machine, the face-plate bei-n gremoved to show the arrangement of the rolls. Fig. 2 isalongitudinalsectional view of the machine, showing.,r the die-blocks and followers.

Similarnumbers of reference designate corresponding parts throughout.

In the drawings, 3 indicates the main frame,

which is formed of a heavy casting. Through the upper portion of thiscasting a longitudinal perforation i is formed, and `in this perforationthe hollow shaftis journaled,being provided at its rear end with thedriving-pulley keyed thereto and operated by a belt. 'lhe forward end ofthe shaft 5 has the enlarged portion 5', which is provided with atransverse slot adapted to receive the dicblocks 7 7 and followersS 8,and in which slot these dic-blocks and followers are movabletransversely across the enlargement 5. rl`he dic-blocks 7 7 have theirinner surfaces either to taper the end of the wire introduced betweenthem or adapted to reduce the size of its cross-section. 'lhe innerIends of the followers 8 8 are adapted to fit against the outer ends ofthe die-blocks, while the outer ends of these followers are rounded tomove over Serial No'. 393,906- (No model.)

the rounded surfaces of the rolls 9 0, which surround the enlargement 5'ofthe shaft 5 and are contained in a circular chamber il', provided inthe enlarged face 32 of the casting 3. Each of the outer rolls lO-lO isjournaled in a bearing drilled in the enlarged face 3a of the casting 3and extending` the length of the. rolls. The circumference of cach ofthese rolls l0 10 is nearly surrounded by the drilled bearing,thatportion of the circumference of the rolls 10 10 extending from theIbearings forming roller-bearings for the rolls 9 9, the number of rollsin each circle being the same.

The rolls and other interior mechanism of the machine are held in placebythe faceplate 1], which is bolted to the enlargement 32 of the casting3,and which is provided with a central perforation l2, through which therod or wire is inserted between the die-blocks.

As the hollow shaft 5 is rapidly revolved the rounded bearing-surfacesof the followers 8 S ride over the surfaces of the rolls 9 9, fornr ingroller toggle-joints and subjecting the wire or rod inserted between thedie-blocks to a rapid hammering or, rather, kneading process, whichcompresses the wire or rod in its cross-section and increases itslength', or by the use of proper dies the endet` the wire is elongatedto a point. By the use'of the rolls 10 10, forming roller-bearings forthe rolls S) 9, the friction on these rolls is greatly reduced, asharper blow is struck, and the life of the machine is increased, owingto the reduced wear coming o n the rim in which these rolls areordinarily incloscdlaud against which they bear.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. In a swaging and pointing machine, the combination,with die-blocks and followers for the same, working in a transverse slotprovided in the end of a revoluble hollow shaft, of rolls surroundingsaid shaft and. arranged to bear alternately on the followers, and asecond set of rolls journaled in bearings in the casing and surroundingand bearing against said trst rolls, as described.

In a swaging and pointing machine, the

combination, with the die-b10eks T '7 and fob lowers S S, movable iu thetransverse Slot of the enlarged end of the shaft 5, of the rolls Si il,surroumling said enlargement and' a1'- ranged to bem' alternatelyagainst the rou uded surfaces of the followers as the shaft is rewlvml,:md the rollslO lO, journaled in the Casing surrounding the whole toform rollerbearings folsaid rolls, as described.
